Abstract: ABSTRACT      An electrical connector receptacle comprises an insulating housing having a plug receiving end and a plug receiving cavity extending into the plug receiving end.          A plurality of side-by-side stamped and formed conductors are insert moulded in the housing and have intermediate portions embedded in the housing between one of the internal side walls of the opening and the adjacent external side wall of the housing.  First end portions of the conductors emerge from the one internal side wall of the opening proximate to the plug receiving end and extend diagonally from the internal side wall into the cavity, these first end portions serving as spring contacts.  The second ends of the conductors emerge from the adjacent external side wall at a location adjacent to the rearward end of the housing.          Stamped and formed metallic mounting posts are embedded into the housing and extend from the adjacent external side wall.          These mounting posts are intended for soldering into metallic pads on a circuit board mechanically to secure the housing to the circuit board. In a method of manufacturing the connector receptacle, the conductors and the mounting posts are fed in strip form into an injection moulding apparatus comprising a mould cavity conforming to the shape of the housing.

Abstract: Case 1-12163/1+2/=            Process for the production of washing powders of stabilised or     enhanced appearance which contain fluorescent whitening agents Abstract of the Disclosure The invention relates to the production of washing powders of stabilised     or enhanced appearance which contain a fluorescent whitening agent of the formula   or of the formula   wherein R1 is hydrogen or chlorine, and M is hydrogen, an alkali metal or ammonium ion. The stabilising    or enhancement of the appearance is effected by first dissolving or dispersing the fluorescent whitening agent in a mixture of water and a polyvinyl alcohol or polyvinyl pyrrolidone which is soluble or is able to swell in water, adding this solution or dispersion to  the washing powder slurry and drying the slurry. The solution or dispersion can also be subsequently sprayed onto the dried residual washing powder. The appearance can be further enhanced by employing a poly-ethylene glycol, a surfactant containing ethyleneoxy and/or propyleneoxy groups, and/or a cellulose ether, in addition to the polymer in the solution or dispersion. The solution or dispersion comprising fluorescent whitening agent and polymer can also alternatively be dried, preferably by spray drying, to produce a preparation which, after it has been suspended in water, can also be added to the washing powder slurry. The slurry is then dried, preferably by spray drying.

Abstract: P.C. 6157 STEREOTACTIC SURGERY APPARATUS AND METHOD                     Abstract A stereotactic surgery frame with x-ray detectable fiducial markers (100, 102, 104) is presented.  The frame is fixed with respect to a patient's anatomy and defines a predetermined three-dimensional coordinate system (X, Y, Z) in which surgical devices may be precisely positioned.  A desired target area of the anatomy is detected in a cross-sectional CT scanner depiction of the combined stereotactic frame and patient anatomy.  The target's X, Y, Z coordinates with respect to the frame are calculated based on three non-collinear fiducial points (F1, F2, F3) located within the cross-section and having known coordinates both with respect to the frame and with respect to the target.  Thus, the surgical device can be precisely applied in the target area.

To accomplish this, the vent valve is of the ball type which engages two oppositely disposed conical ball seats (44, 70), one of which is allowed to move laterally with respect to the other, causing the ball (66) and ball seats (44, 70) to be "self-centering" and resulting in a uniform compressive force being applied over minor circum-ferences on the ball (66).  The use of conical ball seats (44, 70), one of which is laterally movable, also permits the axes of the conical ball seats (44, 70) to be non-parallel and/or non-concentric without hindering the operation and effectiveness-of the vent valve.
